FASTENER.

Application filed .Tune 14, 1924. Serial No. 719,923.

This invention aims to provide an im-1 proved separable fastener, prefer-ably, though not exclusively, for use in securing automobile curtains to the body of the car.

In the drawings, which illustrate a preferred embodiment of my invention Figure 1 is a front elevation of a preferred form of fastener; Y

Fig. Q is a rear elevation of a preferred form of stud, herein shown as attached to an automobile curtain;

Fig. 3 is a section, partly in elevation, ou the line 1l-3 of Fig. 1, showing the stud partly entered within the socket;

Fig. L is a section similar to Fig. 3 showing the stud locked to the socket;

Fig. 5 is a front elevation of a preferred form of socket; and 4 Fig. 6 is a side elevation of the preferred form of socket.

Referring to the drawings andv to the preferred form of fastener selected for illustrative purposes, I have shown a stud in cluding` a contractible and expansible head 1, herein shown as relatively short and integral with a back plate 2. The stud may be secured to a curtain 3 by prongs 11 struck up from the periphery of the back plate 2 and these prongs pass through the curtain and are defiected by an anvil part against an inwiufdly bent flanged portion 5, both of which'vare integral with a front plate 6 located on the opposite side of the curtain. rThe front plate also presents a concaved portion 7 surrounding' an aperture 8, the purposes of which are more fully hereinafter described.

The preferred forni of socket, as illustrated in the drawings, is vof the flush type and pre scnts a preferably hexagonal body portion 9 counter-sunk into the body 10 of the car and embracing the hexagonal head 11 of a screw 12 which holds the socket in place on the body of the car. A preferredA form of means for holding the head of the screw in a fixedrelation to the body 9 of the socket comprises indented portions 13, of which there is one pressed from each flat'side of the y then contracts andthe reversely bent porbody of the socket. y

The head 11 of the screw 12 is seated 'against these indented portions and held thereagainst by rolling a portion of the body 9 of the socket overVA the edge of the head 11 and clenching'it against the face thereof.

Thus the head'll of the screw is held in a fixed relation to the socket, as best illustrated in Figs. 3 and 4.

rI"he socketalso presents a front face 141-, which is secured to the hexagonal flange integral with the outer end of the body,-thus presenting a flange which overlies the body portion 9 sufficiently to conceal the hole in the body of the car into which the body portion of the'socket lits when secured to the body of the car.

The front face 14e also presents a studreceiving aperture 15 for reception of the head 1 of the stud which may be locked therein against contraction by a locking shoulder 16 located between a press-button 17 and a sealing disc 18, all of which are normally urged forward into apertureclosing position by a spring 19 interposed between the head 11 of the attaching screw and the sealing disc 18. The press-button 17 is preferably, as illustrated, pressed from the sealing disc and the locking shoulder is pref erably located adjacent the fronty face of the sealing disc and engages the inside of the contractible and expansible head, when engaged in the stud-receiving aperture, to prevent contraction thereof andy separation from the socket by a strain on the curtain not intended to separate the stud from the socket. When the stud and socket are locked vto- Thus the necessary length of thej press--4 button beyond the front face of the` socket is greatly reduced so that the press-button will not be an objectionable projection upon which clothing'may catch.'

`The stud may be secured to the socket by y merely forcing the head 1 of; the stud into the stud-receiving aperturel. The head tions 20 of the head engage the locking shoulder 16 and forces the press-button, locking shoulderv and sealing disc inwardly against the pressure of the spring 19. After the stud is fully engaged with the aperture, the head expands and the locking shoulder is forced by the spring 19 into the head of the stud Where it engages the reversely bent portions 2O and locks the stud With the socket.

Separation of the fastener is effected by grasping the lower edge of the curtain 3 and exerting a slight outward pull thereon at the same time pressing inwardly on the press-button 17 to vdisengage the locking shoulder from the inner periphery of the reversely bent portions of the stud, thereby to permit contraction of the head and Withdrawal thereof from the socket.

The type of fastener herein described and illustrated is very much simplified over other known types of fasteners which are locked on all sides when secured to each other. in

`my preferred form of stud, there is no mechanism to get out of order, and in the preferred fo ni of socket there is little or no mechanism to get out of order. The number of parts in the stud has been reduced to a minimum Without any increase in the number of parts in the socket, thus reducing the cost of such types of fasteners Without affecting the durability thereof.

TWhile l have shown and described a preferred form of one embodimentof my invention, it Will be understood that changes involving alteration, emission, substitution and reversal of parts, and even changes in the mode of operation, may be made Without departing from the scope of my invention, Whichis best defined in the follo 'ing claims.

Claims:
